1. Geo-Region of the Month – Paterson Province, Western Australia

Each month Geoscience Australia will highlight a range of significant products released over the past 10 years which relate to key Australian mineral provinces and may be of interest to current explorers.

This month’s Geo-Region is the highly endowed Paterson Province in Western Australia. The work was conducted as part of the Onshore Energy Security Program and the National Geoscience Agreement with the Geological Survey of Western Australia. Highlighted products, which are available as free downloads, include:

  1. Paterson airborne electromagnetic survey - interpretation report. This report documents data acquisition parameters of the 2007–08 Paterson airborne electromagnetic (AEM) survey along with summaries of the geology and mineral systems of the Paterson Province and interpretations of AEM data.
  2. Paterson airborne electromagnetic survey - data. Data from the Paterson AEM survey was collected along both east-west (Paterson North area) and northeast-southwest (Paterson South area) flight lines spaced mostly between one and six kilometres. It covers the Paterson Province with the exception of the Rudall River (Karlamilyi) National Park.
  3. Palaeovalley map of Western Australia, Northern Territory and South Australia. This thematic map shows the distribution of Australia's arid and semi-arid zone palaeovalley systems in Western Australia, South Australia and the Northern Territory, including those in the Paterson Province. This map, which was compiled for the Palaeovalley Groundwater Project funded by the National Water Commission, provides information about water resources to support mining in the region as well as the distribution of palaeovalleys that may have potential for sandstone-hosted uranium deposits.
  4. Solid geology interpretation of the Paterson Province at a 1:250 000 scale. This report presents a solid geology interpretation of the Paterson Province, extending from the Canning Basin in the north to the Officer Basin in the south.
  5. Paterson drill hole database. This contains digital data, including geological logs, for more than 4300 public domain historical drill holes.
  6. Ages of gold-copper mineralisation and associated granite magmatism in the Paterson Province. This document reports the age of the Telfer gold-copper deposit (850–840 Ma) using U–Pb analyses of monazite and xenotime that form part of the ore assemblage. It also reports age determinations for a suite of granites from the O'Callaghan's Supersuite, including the granite associated with the O'Callghan's wolfram–copper–zinc skarn (~805 Ma).
  7. Age of uranium mineralisation at Kintyre. These documents report the age of mineralisation at the Kintyre deposit (840–830 Ma), which appear to coincide with the inversion of the Yeneena Basin during the Miles Orogeny (see (1) above).

2. In situ iron ore resources maps (2012 edition) released

Geoscience Australia has released two new 1:10 million scale colour map sheets, Australian In Situ Iron Ore Resources 2012. Sheet 1 shows in situ iron resources (hematite) of geological regions. Major hematite-type iron deposits are classified according to the resource size and plotted on the regions. Sheet 2 shows in situ iron resources (magnetite) of geological regions. Major magnetite-type iron deposits are classified according to the resource size and plotted on the regions.

The map sheets are available as a free download.

3. Seismic data released for Lower Lesueur Survey in Western Australia

The Lower Lesueur Seismic Reflection survey was undertaken during February and March 2011 to evaluate the carbon capture and storage (CCS) potential of the southern Perth Basin. This project was a collaboration between Geoscience Australia and Geological Survey of Western Australia and is linked to the Western Australian Department of Mines and Petroleum’s South West Hub Project [PDF 3.25MB]. Funding was provided from the Western Australian Government’s Exploration Incentive Scheme and the Commonwealth Department of Resources, Energy and Tourism’s Pre-competitive geological storage data acquisition program.

Seismic reflection data was recorded along six traverses near the townships of Harvey, Yarloop and Cookernup to define a target site for further investigation into a possible site for a CCS pilot project. In addition, the new seismic data in the area will expand the scientific knowledge for water resources, potential geothermal sites, oil and gas prospectivity and natural gas deposits. The interpreted survey results were used to define the location of a stratigraphic data well, GSWA Harvey 1, which was successfully completed in March 2012 at a depth of 2945 metres.

The processed SEG-Y data, TIFF images, location information and gravity data are available as a free download.

4. Workshop on new seismic and MT datasets in the northern Yilgarn Craton region, Western Australia

There will be a full day workshop on Wednesday, 27 February 2013 in Perth to present the results of new seismic reflection and magnetotelluric data collected for the 2010 Youanmi and 2011 Southern Carnarvon seismic surveys. These surveys extended across the northern Yilgarn Craton in Western Australia from the Southern Carnarvon Basin, across the Narryer and Youanmi terranes and into the Kalgoorlie Terrane of the Eastern Goldfields Superterrane. The survey and workshop are a joint venture involving Geoscience Australia and the Geological Survey of Western Australia.

To obtain details on the workshop, please email narelle.neumann@ga.gov.au; or phone +61 2 6249 9429.

Registrations are through the Geological Survey of Western Australia.

5. Update on geophysical data releases

Geoscience Australia is managing the data acquisition programs in New South Wales, Queensland, Western Australia and South Australia.

The current status of Geoscience Australia's geophysical survey data acquisition is available in a comprehensive table.
